Abstract (en)
A pile arrangement (1) for vibration driving, which pile arrangement (1) comprises a stem (2) extending in a longitudinal direction between a first end (2a) and a second end (2b), which first end (2a) is arranged to be positioned below the second end (2b) during driving of the pile arrangement (1); and a base structure (3) arranged at or in proximity to the first end (2a). The base structure (3) comprises a plurality of longitudinally open cells (6), which cells are symmetrically arranged around the stem (2) in the cross section of the base structure (3), each cell (6) being defined by a plurality of cell walls (4, 5) extending in the longitudinal direction. Each cell (6) has a height-to-width-ratio calculated as the longitudinal extension of the shortest cell wall (4, 5) defining the cell (6) divided by a significant distance (Sd) of the cell's (6) cross section. The height-to-width-ratio is in the range of 1 - 30, wherein said significant distance (Sd); for cells (6) having a non-triangular cross section, is constituted by the shortest distance between two mutually non-adjacent sides of the cross section, and for cells (806) having a triangular cross section, is constituted by the shortest of the cross-sectional triangle's base and height.
